A retrospective population-based study of injury types among elderly in Taiwan.
Summary of "A retrospective population-based study of injury types among elderly in Taiwan."
The aim of the article was to investigate the injury types and medical utilisations among patients more than 65 years in Taiwan. The data used in this study were obtained from the years 1997 to 2008 of the National Health Insurance Research Database (NHIRD). The patients with the age of 65 years and older as well as with ICM-9-CM discharge injury principal diagnoses 800-959 were included in this study. SPSS 18.0 was used for data analysis. The results showed that there were 518,601 older adults hospitalised because of injuries in the period of study. The average age among them was 76.1 years old and 51.7% of them were females. The common causes of injury were falls and motor vehicle accident. The average number of operations that patients received was one, and the average length of stay was 9.1 days. The total medical expenditure was over NT$ 28.9 billion, and the average expenditure was NT$ 55,738. The factors associated with deaths were sex, ages, co-morbidity disease, level of care, number of operations, length of stay, expenditure of medical care, injury types and causes of injury. This study concludes that in order to decrease the incident of injuries in elder patients, the education of preventing falls and traffic safety should be promoted continuously among elders.

Medical and Biotech [MESH] Definitions
Population Surveillance
Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.
Sentinel Surveillance
Monitoring of rate of occurrence of specific conditions to assess the stability or change in health levels of a population. It is also the study of disease rates in a specific cohort, geographic area, population subgroup, etc. to estimate trends in larger population. (From Last, Dictionary of Epidemiology, 2d ed)
Retrospective Studies
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Sampling Studies
Studies in which a number of subjects are selected from all subjects in a defined population. Conclusions based on sample results may be attributed only to the population sampled.
Proportional Hazards Models
Statistical models used in survival analysis that assert that the effect of the study factors on the hazard rate in the study population is multiplicative and does not change over time.
